WATER-STILL.

as will enable others skilled in-the art to which it appertains to make and use the same.

My invention relates to improvements in water-stills, and more particularly to portable stills for family use; but the principles involved would be equally applicable to stills of all sizes and for all purposes.

At the present time great attention is being given to the matter of pure water for drinking and household purposes, and my object is to provide a cheap and convenient means for obtaining the same.

'In the drawings herewith accompanying and making a part of this application, Figure 1 is a plan view of my improved still, the top being removed. Fig. 2 is a vertical sectional view taken on line X X of Fig. 1; and Fig.- 3 is a central vertical sectional view of the condensing-chamber and a portion of the steamconduit, taken on line Y Y of Fig. 1.

The same letters of reference refer to like parts. I

In said drawings, A represents a reservoir for containing water and in-which steam is generated. This reservoir may be of any convenient construction; but I find that the capacity of a given stillis greatly increased by dividing said reservoir into upper and lower compartments Band 0, respectively, and connecting them by conduits D, the lower compartment 0 being shallow. The reservoir is provided with a suitable inlet-pipe E, by means of which the reservoir is filled. Leading from said reservoir is a tubular conduit F, opening at the top into a condensing-chamber G. The condensing-chamber is comparatively shallow and of much greater extent than the conduits F andiI, entering the hottom thereof, so that the entire surface of the condensing-chamber, except where said conduits enter, is exposed to theair, the air circulating freely aroundthe conduits I and on all sides of the condensing-chamber.

mediate between the reservoir and said con-- creasing the efficiency of the apparatus. The

chamber receives the initial force of the steam, whenceit is distributed through the conduits. Itis found useful to make these conduits oval; but this is not necessary.

To direct the water which results from condensation into the cond uits and thence into the tank, I incline the bottom of the condensingchamber downwardly from two sides to a common point-coincident with the center line of the conduits leading from the condensingchamber to the tank. i

To prevent any water from returning to the reservoir through the steam-conduit, I extend the top of it above the bottom of the condensing-chamber, as seen at J.

To obviate the danger of an explosion from point a safety-valve K. The water-tank is provided with asuitable faucet L for drawing off the water.

To many people pure distilled water is not agreeable and needs to be aerated. To properly and conveniently aerate the distilled water, I insert in the tank a perforated pipe M, extending along the bottom of the tank,

through which air can be introduced into the 4 water below the surface. The aerating-pipe projects through the top of the tank and terminates in a suitable fixture for'the attachment of an air-pump, (not shown,) by means of which air can be forced into said pipe, whence it escapes from the perforations N and passing up through the water thoroughly aerates it.

For convenience in handling the tubular steam-conduit is made in two sections, the point of division being between the reservoir and tank, the two at O.

To. operate my improved still, I, introduce parts telescoping, as seen a suitable quantity of water into the reser- I voir and place it upon the stove or other heat- 7 ing apparatus. As soonias the steam begins to generate it passes upwardly through the conduit F into the condensing chamber, whence it is distributed through the series of conduits I, condensation taking place both in said chamber and upon the walls of said conduits.
